Hey all,

When i go to leave for work my r33 wont start, it takes about 4 attempts before it starts and when it does start it runs very rough and coughs and splutter but after about 30 seconds it runs normally.

Can anyone help please?\

Cheers

not always

when my afm had dry joints the first time would intermittently break down mainly when cold until it got so bad it would just limp

had coil packs do the same thing break down when cold but get better when hot

primmed the fuel pump 5 times stilll struggles to start, the car goes like a rocket after its started once you get in running it comes good after about 10 seconds of running doesnt cough or limp , it just never wants to start

This is from the R32 Engine Manual for "difficult to start - engine cold":

1. Fuel enrichment from engine temperature sensor not working (sensor not working at cold)

- disconnect sensor - any difference?

- sensor resistance value?

- sensor voltage value?

2. Idle speed control (AAC) not working

- AAC valve closed?

- AAC valve plug disconnected?

3. Start time enrichment not working (check through CONSULT)

4. Cranking speed too low (sus battery, sus starter motor)

(presumably same or very similar for RB33)

hi, had a verry similar problem with my r33 gts, ended up being a leaking injector o-ring, pulled fuel rail on and primed fuel pump to check of any where leaking easy to check and easy to fix if thats your problem, 5 cent part big problem though.:thumbsup:

    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
